Parses a resource file containing a UI definition
and merges it with the current contents of @builder.
This function is useful if you need to call
[method@Gtk.Builder.set_current_object] to add user data to
callbacks before loading GtkBuilder UI. Otherwise, you probably
want [ctor@Gtk.Builder.new_from_resource] instead.
If an error occurs, 0 will be returned and @error will be assigned a
GError from the %GTK_BUILDER_ERROR, %G_MARKUP_ERROR or %G_RESOURCE_ERROR
domain.
It’s not really reasonable to attempt to handle failures of this
call. The only reasonable thing to do when an error is detected is
to call g_error().
